The Glaswegian involved here, just got involved, the Police managed to pepper spray him? And he still flattened this person.
I am from Liverpool UK, and we have an affinity with Jocks. We both have a particular move, the head butt! But describe it differently.
We Scousers call it a Liverpool Kiss, Jocks say, The Glasgow Hand Shake!
Same move, you bring the forehead forward, use the strength of the neck, and speed gives the strike power. The spot you aim for, the bridge of the nose.
When as a kid you have only a soccer ball (Football in the UK) to play with, a plain wall, end of a building? And you can keep the ball in the air for ages.
Also, strengthen's the neck.
I spent 5 years as a Bouncer in Liverpool Clubs. Still, have a straight nose!
Had problems at the door, mostly locals, with a few pints in them.
Never had a problem with a Jock, ever.
Fights do not have wind ups as in the USA, IE two men (Kids?) come out of a Bar, bad language, throw a few punches, may be a nose bleed?
A quick description of a three man altercation, two of them, and one of me.
A Thursday night, normally a quiet night, actually my first night, The Blue Angel, on Seal Street. My Buddy and I had moved on from The Cavern Club, of Beatles fame. I had been at the cavern for 4 years, 1960, till 1964.
Got stabbed twice there. Unusual really, mostly teeny boppers.
This night at the Blue Angel, Larry had gone down stairs, where the band and bar were, for a couple of soft drinks for us.
Most of the crowd were Liverpool University people, Uni scarf, Jeans, and sweaters. Of course, I did not know any of them, when I asked for members cards? "Tony knows me" He was a crippled chap, walked with two sticks, the ones you put your arms through. Tony sat at a little desk, about 4 yds into the passage leading in from the Street.
He could arrange for visitors to be signed in, not a big deal. Normally!
Two men, definitely not Uni types! We're in front of his desk " Mick, these two gentlemen are not members, and they are not with a member"
One over 6ft, nasty looking, skinny both in suits. His Buddy (I would have said, Mate at that time) my height 5'10" but heavy set. Wearing thick black rimmed glasses. You know the type, TROUBLE!
Larry still not back from (probably chatting up the Bar Maid) getting our soft drinks.
"Sorry Lads, no one to sign you in, you can't come in," Mr. Glasses said "We are already in, aren't we" at the time I wore rimless glasses. So I took them off, slid them into the case in my Jacket Pocket.
He grabbed his specs, said Two can play at that game. My straight left hit his nose, via the glasses! He went down, streaming blood, when we threw him in the Street, he had bits of lens stuck in his face.
Skinny now stepped forward, over the sleeping beauty! Glancing down as he stepped over him... MISTAKE! My right cross put him into the wall, the follow up left hook, put him behind the door.
Where he seemed to almost crouch, I hit him with lefts, and rights, till my arms just about fell off. "HE CAN NOT FALL DOWN MICK!" Tony was yelling.
His coat was caught on the big hinge, that supported the steel door.
By this time Larry had arrived! So we pitched them down the three steps into the Street. We did not call the Police, they left after a while? I reckon.
Fri night, each Uni person, Boys, and Girls. Came in, cards in hands, held up, "Hi Mike, Hi Mike" like a bunch of parrots.
One night and they all knew my name, stayed there a year, then left with the Family for Australia.
Larry was ex SAS, I did not find out, till he passed away, in 2007. I was living in Toronto then, with my second Wife. And the final one, 25 years now.
